Tor 1Z1 d'vhomz't nmg concemL. Be it known thatI, ARTHUR-E BRAoE, a citizen of the United States, residing, at

Waterforchin the county of 'Erie and State .of Pennsylvania, have invented new;.and 'useful Improvements in Automatlc Ollers,

of which the following is a specification. This invention relates to automatic ollers fer-internal combustion engines, the object a at the proper working p'ointirrespective of oftheinvention being 'to combine-with the crankcase of an-engme, means whereby the level of oil'nn the crank case is 1na1nta1ned whether the engine is operating or at, rest,

engines of the character above referred the invention, being "particularly designed with reference to internal combustion env ginesfi'n which the fly wheel or magneto or both revolve in oil "in the vcrank case or an extension or extensions of said case.

Under theolling systems at present in use to, the level'of oil is higher when the engine is at'rest than when theengine' is in operation for the reason that the rapidly revolve" ing fly wheel, for example, picks up a considerablequantity of oiland correspondingly, reduces the level. The present invention aims to trap thissurplus oil and store the same in such a manner,;while the engine is inop'eration, that only the-proper amount ofoil-willremain in the crank case thereby Preventing \the ngine from smoking or. emittingfa nexcess amount of smok is contrary to the trafiicreg'ulations i manycities' and other places and at the same time injurious to the engine in that it results in a rapid accumulation of carbon and a corresponding loss of power and efficiency in the engine With the above and other ob ects m'v1ew-,

the invention consists in the novel construction, combination a'nd arrangement of parts,

as'herein described, illustrated-and claimed' The accompanying drawing represents a vertical sectional view ofthe automaticoiler of this invention, showing the crank case in cross section taken about in line with the fiy wheel.

:Referring to the drawings 1' designates the crank case of an internal combustion engin'e, 2 the crankshaft and 3 the-fly wheel mounted on'said shaft, said parts being of the "usual construction and arrangement with the exception of the crankcase in which I have arranged an 'oil catching. pocket 4 2 rhich Specification of Letters Patent.'

which 'is located above the I normal oil level of the crank case. I

' Exteriorly-of the crank case but connected therewith is anoi-l Well 5-from which an oil feed connection or conduit .6 extends into the crank 'cas e as shown thereby causing, the same level of oilnto be maintained'inthe 'crank case and thcwell When-the engine is not in operation; 7 designates a return conneotion l'eading'from the pocket 4 back to the well 5 theiconnec'tion 7 having a larger hore than the connection 6 so that the oil with an oil reservoir 8 and an oilsupply pipe 9'leading from said reservoir to the well, an

' automatic oil inlet valve 10 which is carried 'by one arm of a, float'lever l1 fulcrumed at 12 on a bracket 13 in'the well 5,16 desi s ing the Heat which is attached to the lever 11 and which by-rising under the buoyant elfect of the oil in the well, closes the inlet valve 10 and'therebycuts' ofi' further flow of oil from'the reservoir 8 tothe well 5.

- The operation of-the oiling mechanism hereinabove described is as follows, -When an engine-- of the class referred to is 'idle or at a standstill, the level of oil in the-crank case 1 and the well .5 is the same. As soon as the engine starts, however,;the'fiy wheel picks up a considerable quantity'of the oil which is caught or trapped in the pocket 4 and which flows freely through the connection 7 into the well 5, further increasing the level of oil in the well so that by means of the float 14, theinlet 'valve 10 is all the more tightly. pressed against its .seatso as to prevent any oil from passing through the supply pipe 9. In this way an excess amolmt of lubricating oil is removed temporarily from the crank case so' as to prevent undue burning and consumption of oilbythe engine and the carrying off -of the same thrdngh the exhaust pipe and muffler; As oil is consumed by the engine, the supply is replenished by the opening of the inlet valve .10 when the oil falls below a certain prede termined level in the crank cast- 1 and therefore in the we'll- 5.

Having thus described my invention,'I claim .1. The combination of a crank case having an internal oil-pocket above the normal oil level therein, an oil 'well located exteriorly of the crankcase, a free oil conduit connecting' saidzwell and crank case below the oil 10 is at rest, and a return connection leading level in said pocket and the crank case whereby a common 011 level is maintained in said pocket and,crank case when the engine from said o'il pocket back to the well and having nection. x

2 The combination of-a crankcase MW in an internal oil pocket above the normal oi level therein, an, oil Well' located exteriorly of the crank case, a free oil conduit alargerbore than said oil feed conconnecting-said well and crank-case below the oil level in said pocket and the crank case whereby a common oil level is maintained in said pocket and crank-case when the engine is at rest, a return connection leading from said oil pocket back to the well. and having in presence of two witnesses.
